JO leader Dinesh Gunawardena said the campaign would begin on January 02 at Sugathadasa indoor stadium.
Leaders of the JO and the SLPP will attend the rally which will tell the people as to why they should elect the SLPP to power at the election, said Gunawardena.
The SLPP candidates will make a pledge on the occasion to bring victory to the villages while safeguarding the country, he said.
However, the SLFP CC has empowered its leader Maithripala Sirisena to suspend the party members who promote any other political party in violation of clauses 26-1, 26-2 and 26-3 of the party constitution.
It has decided to send letters by registered post to all its MPs and provincial councilors, informing them of the decision.
SLFP general secretary Duminda Dissanayake said disciplinary action would be taken against anyone who violated the party constitution by promoting any other party.
Noting that policies, not persons, were important, he said violators would be disciplinarily-dealt with irrespective of their positions.
